SIMULATION ON A TEST MACHINE OF THE ACTUAL PATH OF A VARIABLE SPACING TYPE RAILWAY AXLE

SIMULATION SUR MACHINE D'ESSAIS DU PARCOURS REEL D'UN ESSIEU FERROVIAIRE A ECARTEMENT VARIABLE

The S.N.C.F. Test Center at Vitry has been entrusted with the development of a test machine for the simulation of the actual path of a railway axle. Previously, tests in service on track have been carried out in different conditions and for different track qualities. Processing the results in a computer has enabled the definition of the signals for the two excitation paths (horizontal and vertical). From this data it has been possible to design and develop a test machine. Its basic principle is to transmit to the axle in a fixed position the horizontal and vertical stresses through a frame hinged about a fixed point. Stresses are applied by means of slave-controlled hydraulic jacks. The excitation signals transmitted to these jacks are elaborated by a program from data previously recorded and stored.
